INTL0101 Flag Attribute if anything is on same line

[COsborn2]

public enum Foo
{
    [A]Bar
}

should be

public enum Foo
{
    [A]
    Bar
}

Also consider
[A]public void Bar() { }

I took a stab at this and think I've got something to PR, but do you think this is worth testing for too, where a property / method signature / etc is split on multiple lines? Personally, I don't think I've seen anyone do this, but it compiles so it's possible...

        [A]int
Prop {get;set;}

@grantwinney yea I am a little less concerned with that particular case. It would be nice to address, but that could be a follow up issue/PR as well.

Sounds good. I thought it might be a quick change, but now I'm not so sure. I don't know if it can be handled in context.RegisterSymbolAction or if it might involve invoking context.RegisterSyntaxNodeAction. Since it might be a bigger change, I left it out of the PR.
